Abstract
The invention aims to provide an internally-cooled drill good in cooling effect. The internally-cooled drill comprises a shank and a cutting edge portion disposed at the end of the shank. The shank is provided with an inflow passage in a penetrating manner. The cutting edge portion is axially provided with a chip groove in a parabolic shape. The chip groove is provided with a cooling water outlet communicated with the inflow passage. The internally-cooled drill is characterized in that the cooling water outlet inclines towards the shank. The internally-cooled drill is provided with the moderate cooling water outlet, chips produced during drilling can be smoothly and automatically removed from the chip groove, the fact that cooling water constantly and smoothly flows out of the cooling water outlet to continually cool a bit is guaranteed, cooling effect is guaranteed, and the service life of the bit is prolonged.
Description
Technical field
The invention belongs to bit technique field, specially refer to a kind of interior cold brill of good cooling results.
Background technology
Drill bit can discharge a large amount of heat in boring procedure, if can not be cooling in time, likely can have influence on boring effect, even can damage drill bit.Interior cold brill can be introduced the front end of cooling water to drill bit from drillstock, thereby can in the process of boring, be drill bit cooling.But existing interior cold brill has only been realized cooling water has been caused to drill bit place, does not but consider and how to make cooling water flow out from drill bit more glibly.The chip producing in boring procedure is likely blocked the outlet of cooling water, affects cooling effect.
Summary of the invention
The object of the invention is to propose a kind of interior cold brill of good cooling results.
Interior cold brill of the present invention comprises drillstock and is arranged on the blade of drillstock end, described drillstock runs through and is provided with into aquaporin, described blade offers parabola shaped chip area vertically, described discharge launder is provided with and the coolant outlet that enters aquaporin and communicate, and key is the oblique drillstock direction of described coolant outlet.
The oblique drillstock direction of coolant outlet, can be in boring procedure, push the chip of generation to drillstock direction along discharge launder, thereby chip is discharged to boring, avoid accumulation of debris boring in and coolant outlet is stopped up, cooling water can flow out from coolant outlet all the time swimmingly like this, cooling to drill bit enforcement constantly, has ensured cooling effect.
Further, the both sides cell wall of described discharge launder is equipped with several coolant outlets, the coolant outlet of both sides cell wall is staggered, the staggered coolant outlet in cell wall both sides sprays cooling water simultaneously in discharge launder like this, can avoid the cell wall place of accumulation of debris in any side, affect chip and discharge.
Interior cold drilling through of the present invention arranges suitable coolant outlet, the chip that can successfully boring be produced is discharged in discharge launder, thereby ensure that cooling water can flow out from coolant outlet all the time swimmingly, implement cooling to drill bit constantly, ensure cooling effect, extended the service life of drill bit.
Brief description of the drawings
Fig. 1 is the structural representation of interior cold brill of the present invention.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as effect and the operation principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As shown in Figure 1, the interior cold brill of the present embodiment comprises drillstock 1 and is arranged on the blade 2 of drillstock 1 end, described drillstock 1 runs through and is provided with into aquaporin 3, described blade 2 offers parabola shaped chip area 4 vertically, described discharge launder 4 is provided with and the coolant outlet 5 that enters aquaporin 3 and communicate, key is the direction of the oblique drillstock 1 of described coolant outlet 5, and the both sides cell wall of described discharge launder 4 is equipped with several coolant outlets 5, and the coolant outlet 5 of both sides cell wall is staggered.
Oblique drillstock 1 direction of coolant outlet 5, can, in boring procedure, push the chip of generation to drillstock direction along discharge launder 4, thus by chip discharge boring, avoid accumulation of debris boring in and coolant outlet 5 is stopped up.And the staggered coolant outlet 5 in cell wall both sides is simultaneously to the interior ejection cooling water of discharge launder 4, can avoid the cell wall place of accumulation of debris in any side, affects chip and discharges.Cooling water can flow out from coolant outlet all the time swimmingly like this, cooling to drill bit enforcement constantly, has ensured cooling effect.
Claims (2)
1. cold brill in a kind, comprise drillstock and the blade that is arranged on drillstock end, described drillstock runs through and is provided with into aquaporin, described blade offers parabola shaped chip area vertically, described discharge launder is provided with and the coolant outlet that enters aquaporin and communicate, and it is characterized in that the oblique drillstock direction of described coolant outlet.
2. interior cold brill according to claim 1, is characterized in that the both sides cell wall of described discharge launder is equipped with several coolant outlets, and the coolant outlet of both sides cell wall is staggered.
